An early phase of delivery (Phase 1) has been implemented and the results of this will help inform future phases.
Phase 1 of the 20mph rollout has been delivered across the following areas:
- Camelford
- Falmouth and Penryn
In March/April 2022, 76% (Falmouth and Penryn) and 86% (Camelford) positive feedback was received in support of Phase 1.
We reviewed all existing 30mph speed limits, with the majority reduced to 20mph. We selected these areas for many reasons. This includes, but not limited to:
- Deliverability within required timescales
- Building on existing or advancing 20mph provision, closing gaps
- Mix of built-up areas, towns and rural villages, providing optimal monitoring opportunities
- Synergy with other investment.
The results
20 out of 22 sites saw positive reduction in traffic speeds.
Falmouth and Penryn
- Reductions in mean speed of up to 6.9mph and reductions in 85th percentile (speed at or below which 85% of vehicles are travelling) of up to 8mph
Camelford
- Reductions in mean speed of up to 5.7mph and reductions in 85th percentile of up to 5.5mph
Targeted support will be provided to non-compliant sites.
Data collection and monitoring
We will collect and monitor various data sets before and after the delivery of each phase. This data will include (but not limited to):
- Collision and casualty data
- Traffic speeds and volumes
- Air quality data (where able)
Other data collection and monitoring could include:
- Surveys of school children and parents. This is to see if the 20mph has made any difference to their travel to and from school, and within their social activities.
- Working with Parish and Town Councils to get qualitative information. This will be the positive or negative impacts communities have experienced.
